Antelope Island State Park

Current Conditions

 Last Updated: 11/6/2024


Insects: During warm months, insects are present on the island and emerge at different times.

  • Biting gnats (no-see-ums) not currently active emerge in the spring (April – June).  These are very tiny biting flies. Insect repellent is ineffective against the gnats; fine-mesh head nets are recommended.
  • Midges not currently active are non-biting flies that form columns along the causeway mid-spring through early fall. These are what cover your windshield while driving to and from the island.
  • Mosquitoes not currently active are present from mid- spring through early fall. Insect repellent is effective. Note: West Nile Virus has been found in Davis County.
  • Brine Flies not currently active are non-biting flies that cover the shorelines and occasionally move onto land early-summer through fall. These flies are harmless and move out of the way when approached.
